As announced yesterday by Microsoft, the Office 2010 products will be 64bit only in the future. Well, no surprise there, we already knew that. But they went even further.
Because of their experience with customer implementations of the 2007 series they recognize that having Windows Server 2008 and SQL Server on 64bit is a must for ensuring the best performance possible. Therefore the 2010 series of products will only be available on those versions!
Also, on the client side there will be an improvement as Internet Explorer 6 will not be supported anymore.
So, to summarize:
- SharePoint Server & Project Server 2010 will be 64-bit only
- SharePoint Server & Project Server 2010 will require 64-bit Windows Server 2008 or 2008R2
- SharePoint Server & Project Server 2010 will require 64-bit SQL Server 2005 or 2008 (But you should choose 2008)
- SharePoint Server & Project Server 2010 will only support Internet Explorer 7 or 8
